i dont think many ppl kno much about spectroscopy here

The numeral indicates the charge on a variable-cahrge metal. Metals such as Iron can have variable charges- II (+2) and III (+3) for example. You can seperate by filtering or sometimes crystillization. ANd the increase in pH would screw up your electrolysis how? so it shouldnt matter. However depens wat the purpose of the electrolysis is.

Out of curiosity, Have you made kno3/sugar propellant? If you heat in an oven (cooking) even the highes temp will not set it off, let alone 350 degress F. So using an oven is perfectly safe, however u still should be present at the time.

Heat the sugar + kno3 in a oven, add syrup mix and heat some more till like almost all the water is out. IF u want it maleable dont heat it to much. THe best thing howevedr is to heat it till it strarts to bubble and crust over then load that directly in the casing and quickly punch a core. It will harden on cooling then and make the propellant good burning.

add sugar syrup- corn syrup.

I think one of the acids is responsible for this

Adding h2o2 to a solution of ammonium dichromate causes it to turn black- no ppt I dont think. Adding HCl causes it to turn brownish (originally orange). Whats happening??

I also heard that exlax has indicator in it- although it never worked.

Just use like the brown paper stuff u get at the grocery store. Roll it up on a stick while adding elmers glue.

the heat and pressure would most likely melt then burst the casing. However if you had it really thick it may work. For really small motors it may work.

also, wen u print on like an overhead, it washes of real easily cuz no ink absorbed.

what? h2o2?

what is it? In a question it said which has the most lattice energy: K2O, MgO, KOH and NaCl. THe answer was MgO and i dont know why.

yes

there was this one question about complexes. It asked which would most likely form ligands in a Co+2 complex: CO, O, or Iodide, and something else. Well, how do you determine which will most likely form the ligand or on?

so the clothes began to break down instantly or after like how many number of washes?

RyanJ, you have no idea what you are tlakign about. MAybe if you bleach a shirt 30 times it may deteriorate, but it doesnt have corrosive properties to shirts thats for sure. I dont know what your bleach contains, but bleach pretty much wont hurt clothes and shoes for that matter.

It shouldnt it will only bleach them. I know of people who used bleach to whiten their shoes. post a picture of them

ughh... it will work for shoes too

You could bleach them

i think the al are sharing an oxygen and 2 other oxygens are on the ends.

Woelen, you never mentioned what happened to the Na+ in that reaction, or is it unknown or did i just miss it?

Ya thats what i was thinking. What i meant is i only have a few ml left of all my strong acid. So i guess i will just go to the hardware store and get soem. Can someone remind me in what section it would be in?

Hmm i guess that would work but i dont want to waste plenty of good acid.

I have sme glass ware that scrubbning and soap wont clean off. Theyre stained by stuff such as metal salts and stuff. What chemical mixture/solution will clean them up? Perfereably ones that do the cleaning without scrubbing.
